Going insain!?!

Samantha • Had our first in November 2015, our second in December 2016, now thanks to and IUD failure we are currently pregnant with our 3rd and couldn't be happier. Maybe I'll finally get a girl.
So my SO and I have been TTC for 5 months and I have decided to quit smoking since it should help us get there. And today is the first day. OMG I want a cig...help.
